Short answer. Yes. Article 1197 of the Civil Code allows courts to fix the duration of a period when the obligation itself does not set one but the nature and circumstances make clear that a period was intended. The court determines what the parties would most likely have agreed to.
What the law says
If the obligation does not fix a period, but from its nature and the circumstances it can be inferred that a period was intended, the courts may fix the duration thereof.

When courts can step in to set a deadline
Article 1197 addresses a practical gap that appears in many agreements: the parties clearly meant performance to happen within some timeframe, but they never specified what it was. The article gives courts the power to fill that gap. The threshold requirement is that the court must be able to infer from the nature of the obligation and the circumstances that a period was indeed intended. If the obligation is one that, by its very nature, cannot be performed instantaneously or indefinitely — like constructing a building, completing a development project, or paying in instalments — a period can usually be inferred.
The standard the court applies
Article 1197 does not let a court impose whatever deadline it thinks is best. The standard is specific: the courts shall determine such period as may under the circumstances have been probably contemplated by the parties. This is a retrospective inquiry — what would these particular parties, in this particular transaction, likely have agreed to if they had addressed it? Evidence of industry norms, the scale of the work, prior dealings between the parties, and the context of the agreement all bear on this question.
When the period depends on the debtor's will
Article 1197 also addresses a related situation: when the contract says performance shall happen whenever the debtor wishes, or at his convenience. This potestative period — a period left entirely to the debtor — effectively gives the debtor a free pass to delay forever. Courts are authorised to fix the duration in this case as well, because an obligation that the debtor can postpone indefinitely at his discretion is not a real obligation. The court intervenes to give the obligation teeth.
The period once fixed cannot be changed
Once a court sets a period under Article 1197, the article is clear: the period cannot be changed by them. The court's determination is final on that issue. This finality prevents relitigation of the same question and gives both parties certainty once the deadline is set. If circumstances later change so dramatically that the period becomes impossible to meet, the parties must look to other legal remedies — such as force majeure or novation — rather than asking the same court to revisit the period it fixed.
